The
seventh-grade science students at West Middle School have been studying
pollution, its causes and effects. Mrs. Sara Bochenek presented an interactive
activity daily.
This
activity began by creating a large topographical map. Landforms such as
mountains, hills, valleys, plateaus and plains were identified.
Next
sponges were added to represent wetlands. Wetlands prevent flooding and hold
pollutants at bay from entering large bodies of water.
After
that wildlife figures were included to the topographical map. Using spray
bottles the students made it "rain". They discussed what bodies
of water were now formed. These lakes, streams, oceans and other watersheds
were formed by runoff and influenced by the surrounding landforms. At this
point the environment was clean and healthy for plants and animals.
Everyone
learned that once the Industrial Revolution started water pollution was a
negative consequence. Erosion, oil spills, salt, chemicals, toxic waste and
acid rain entered the waterways.
Pollution
devastated the environment that the class had created. After another
"rainstorm" the science students observed how the pollution spread.
In some instances it was apparent that the wetlands did their job of holding
back pollution from entering the lakes, streams and rivers.
In
conclusion, students gave suggestions how they could each minimize the amount
of water pollution. Suggestions included picking up dog waste, using less
cleaning products, recycling car oil appropriately, and writing letters to our
government officials to enact better pollution control practices.

Bochenek, West's Instructional Support Coordinator, helps our students
have a better understanding of their world through special speakers, field
trips and lab activities.
